Abstract:Aiming at the shortcomings in the health status assessment of missile launch vehicle power supply systems, a method based on dynamic interval improved gray clustering was studied. An health assessment index system for the power supply system was constructed. A comprehensive evaluation method combining gray relational analysis and analytic hierarchy process was adopted to establish an improved gray clustering model. Taking a certain missile launch vehicle power supply system as an example, and combined with measured data, quantitative health assessment was achieved through normalization, comprehensive evaluation, and cluster analysis. Application results show that the method can effectively evaluate the health status of the power supply system with high accuracy and generality, providing a reliable basis for equipment support.
